udpbroadcastrelay do not start since upgrade to 26.1

[letic]

Hey guys,

I'm not sure if you take report for plugins but since the upgrade to 26.1 the updbroadcastrelay plugin refuses to start. Trying to run it manually I get these errors. I use to run it manually for debugging rules so I know it used to work.

To some degree this seems similar to https://forum.opnsense.org/index.php?topic=50520.0

Some people tested the old kernel and found it not to work either, which is a bit weird still.

We're chasing a bug that prevents interface settings from migrating causing at least 2 different distinctive errors. Not sure if there's a third and fourth one with this daemon and miniupnpd.

To be sure... can you run this from the console?

# pluginctl -m


Cheers,

It works on my system after upgrade.

[franco]

the migration or udpbroadcast or both? ;)

[mnaim]

works for me in 26.1, service running and devices are discovered

Migrated today and udpbroadcastrelay is happily starting here on my Protectli VP2420.

Slightly offtopic, but even tho this isn't a CISCO device their 'Best Practice Guides' do advise to skip VLAN 0 to 5 when setting up your network so when you feel like it please look into that and decide if you want to change your network setup or not :)
